3. Hardware Introduction

The NPort 6250 series has 3 models. A brief description of each
model is given below:

• NPort 6250

Two RS-232/422/485 serial ports and one 10/100Tx Ethernet
port

• NPort 6250-S-SC

Two RS-232/422/485 serial ports and one 100Fx single mode
fiber Ethernet port

• NPort 6250-M-SC

Two RS-232/422/485 ports and one 100Fx multi mode fiber
Ethernet port

Reset Button—Press the Reset button continuously for 5 sec to
load factory defaul ts: Use a po inted o bjec t, suc h as a strai ghten ed
paper clip or toothpick, to press the reset button. This will cause
the Ready LED to blink on and off. The factory defaults will be
loaded once the Ready LED stops blinking (after about 5 seconds).
At this point, you should release the reset button.

Blinking:

Indicates an IP conflict, or, the
DHCP or BOOTP server did not

respond properly or a relay
output occurred. Check the
relay output first. If after
resolving the relay output the
RDY LED is still blinking, then
there is an IP conflict, or the

DHCP or BOOTP server did not
respond properly.

Adjustable pull high/low resistor for RS-422/485

(150 K( or 1 K()

Jumpers are used to set the pull
high/low resistors. The defau lt is

150 KΩ. Short the jumpers to set
this value to 1 KΩ. Do not use the
KΩ setting with RS

-232 mode,

since doing so w il l d egrade the
RS

-232 signals and shorten the

communication distance.

4. Hardware Installation Procedure

STEP 1: Connect the 12-48 VDC power adaptor to the NPort 6250

and then plug the power adaptor into a DC outlet.
STEP 2: For first-time configuration, use a cross-over Ethernet

cable to connect the NPort 6250 directly to your computer’s
Ethernet cable. For connecting to a network, use a standard
straight-through Ethernet cable to connect to a hub or switch.

STEP 3: Connect the NPo rt 6250’s serial p or t (s) to serial
device(s).
